Question 1.1. (TCO 5) Anabolic reactions may be characterized as _____. (Points : 2)
exergonic
breaking large molecules into smaller molecules
forming large molecules from smaller molecules
producing ATP
None of the above
Question 2.2. (TCO 5) Enzymes known as lyases participate in _____ reactions. (Points : 2)
anabolic
catabolic
both anabolic and catabolic
neither anabolic nor catabolic
oxidation-reduction
Question 3.3. (TCO 5) Which of the following statements about fermentation is incorrect? (Points : 2)
Aerobic bacteria will undergo fermentation instead of cellular respiration when oxygen is
present.
Fermentation results in the production of fewer ATP molecules than cellular respiration.
End products of fermentation include ethanol, and acetic acid.
The presence of fermentation end products is useful in identifying unknown bacteria in the
laboratory.
Fermentation is involved in the production of a number of foods, including yogurt,
sauerkraut, and cheese.
Question 4.4. (TCO 5) The metabolic processes called fermentation _____. (Points : 2)
produce substrates for the Krebs cycle
are alternatives for the pentose phosphate pathway
occur only when oxygen is not readily available
occur only when oxygen is readily available
produce substrates for glycolysis
